In a scene, the character played by Galifianakis carries a bag
marked LVM, then scolds another character, saying “Careful, that
is.. that is a Louis Vuitton.”

Louis Vuitton's suit alleges the bag Galifianakis carries is made
by the Chinese American company Diophy, which Louis Vuitton is
also currently suing to try and prevent knock-off items of its
brand from being sold in the United States, the Hollywood
Reporter writes.

Louis Vuitton claims its been "damaged by the consumer
confusion," according to the Hollywood Reporter.
